Controversial bison lottery hunt at Grand Canyon nets four animals
A controversial pilot program to reduce the number of bison at Grand Canyon National Park by shooting them has concluded with four of the animals killed.
More than 45,000 people applied this spring in a lottery for 12 spots to help cull the herd.
Up to 500 bison are roaming the far northern reaches of the park. Officials say they are trampling resources and spoiling the water.
The park also captured 36 bison and sent them to Native American tribes in Oklahoma and Nebraska.
Critics had urged the park to consider relocating the animals targeted for lethal removal.
